Today`s machines produce paper so rapidly that visual quality control is stretched to its limits. New automated systems with cameras and image analysis algorithms manage this flood of paper with no problem – they can even tackle the job with patterned wood and textiles.

The fastest papermaking machine in the world produces a roll of paper approximately 10 meters wide at the rate of 100 kilometers per hour. In less than 20 seconds the paper would cover an area the size of a soccer field. Impo

The use of halogenated flame retardants in plastics is steadily declining because they are volatile, pose an environmental risk and are difficult to recycle. Microcapsules, fibers and melamine resin foams represent some of the chief alternatives.

As successfully as the endless variety of plastics have established themselves on the market, these multifaceted materials show another face when it comes to fire. They melt and feed the flames like the petroleum from which they were ultimately pro

Oxygen and light can alter the taste of foodstuffs. Manufacturers of packaging materials therefore try to protect contents from their influence. The latest approach is to use natural dyes in transparent plastic wrappers that selectively filter light.

Light and oxygen adversely affect the quality of most foodstuffs. In combination they cause various ingredients to undergo photo-oxidation. Fatty food substances become rancid and milk products develop an unpleasant “light-induced” taste. Certai

Many Europeans are now learning to deal with a new currency. But also cash dispensers and cigarette machines must distinguish clearly between euros, the old currencies and counterfeit money. A miniature computer now checks the coins by means of digital image processing.

For users of the new European currency, having adequate safeguards against forgery is a matter of great importance. The paper money incorporates features such as holograms, watermarks, a security thread, and embossed text to

Scientists from Newcastle University are using llama droppings to help combat environmental problems caused by polluted water seeping from abandoned silver and tin mines in the Bolivian Andes.

The project is being spearheaded by Paul Younger, Professor of Hydrogeochemical Engineering at Newcastle University. It has been adapted from a community-based natural regeneration technique which uses waste materials to treat polluted mine waters. Professor Younger pioneered the technique, along with

Researchers grapple with wilt-causing bacteria

It’s the Mike Tyson of plant bacteria,” says Gerry Saddler, of the Scottish Agricultural Science Agency, Edinburgh.

Saddler is referring to Ralstonia solanacearum , the cause of southern bacterial wilt possibly the most important plant disease in the world. French researchers have now sequenced the bacteria’s genome – information that should lead to a better understanding of plant disease, and perhaps new ways to fight it
